Epidemiology[edit]
The most ordinary form of dementia is early onset Alzheimer’s, this form of dementia is more common in older people (age of 65 years old and older) but can also be diagnosed in ages as early as 30 years old. About 5% to 6% of people diagnosed with Alzheimer’s disease develop symptoms before the age of 65. To put this in perspective, if 4 million people have Alzheimer’s about 200,000 to 240,000 people are diagnosed with early onset Alzheimer’s.

Alzheimer’s disease is not considered a genetic disease, but it is more common in families who have pre- existing cases. Research done has shown that the rate of people who develop Alzheimer’s varies by country, but it is more common in developing countries.

The average annual rate of early onset Alzheimer’s disease is 2.4 per 100 people nationwide, however this change by age group. A research study done in 2008 found that the most common age group is 46 - 65 years old and the incidence rate found for this group is 7.2 per 100.000 subjects. However, in 2010 a different research study found 4.2 per 100.000 subjects for the same age group of 46 - 65 years old.

Alzheimer’s is found in both men and women but about ⅔ of Americans that are diagnosed with Alzheimer’s are females. Research has shown that Alzheimer’s is the fifth leading cause of death in those who are 65 years and older and the sixth leading cause of death among all Americans.
